JPS63226415A - Rotary plate driver for bucket device - Google Patents

Abstract

PURPOSE:To set a motor on the upside of a bucket fitting part by forming the rotator gear of a rotary plate into a sloped face in the rotary plate driver of a bucket device. CONSTITUTION:Fitting pins 1 and 2 are provided for a bucket fitting part, and a rotary plate 3 is rotatably attached through a rotary joint 12 to the lower part of the bucket fitting part. On the inner surface of the plate 3, rotator gear 13' is formed in a slope, and a counter bucket 10 and a base bucket 11 are attached to the lower part of the plate 3. A motor gear 13 is coupled with the gear 13'. Since the motor gear shaft becomes inclined, an oil motor 5 can be set on the comparatively narrow upside of the bucket fitting part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary plate drive device for a bucket device equipped with opposing buckets that can be clamped, and in particular to a rotary plate drive device that is attached to the tip of an arm-shaped support of a transportation work vehicle such as a power shovel. The present invention relates to a rotary plate drive device for a bucket device that can be rotated as if it were a wrist part.

The inventor of the present application has developed various bucket devices equipped with opposing buckets that can be clamped, and in the process, the entire bucket device or a portion thereof can be rotated with respect to the bucket mounting portion. I have been doing a lot of research on this.

However, it is extremely difficult to install the rotary plate drive device in the relatively narrow bucket attachment portion. In particular, the bucket attachment part requires two strong blades that stand upward in parallel, and these blades extend across the rotary joint, making the installation position of the rotary plate drive extremely restrictive. It was to be done. The present invention is based on the development of two points: the installation position and the drive mechanism, in order to operate and hang the rotary plate drive device using the oil motor for driving the rotary plate by utilizing the limited space area. The purpose is to Next, to describe the specific structure for achieving the second objective, it consists of a bucket mounting part and a bucket part, and the bucket mounting part has two parallel upright pieces spaced apart from each other at a desired distance. , bucket mounting pins 1 near the front and rear ends of each upright piece.
．． 2, a rotary plate 3 is disposed below the bucket attachment part, a rotation stopper 4.4' is provided at an appropriate position on the rotary plate 3, and the outer side of the parallel upright piece is placed on the rotary plate 3. An oil motor 5 is disposed at a position, a main bucket 11 is provided below the rotating plate 3, an opening/closing body 10 is provided at a position opposite to the main bucket 11, and the opening/closing body is provided at an upper end of the main bucket 11. 10, an opening/closing pin 9 for the opening/closing body 10 is provided, a pivot portion by a cylinder pin 7 is provided at the opposite end of the main bucket 11, and a cylinder pin 8 for opening/closing the opening/closing body 10 is provided at the end of the piston inserted into the cylinder 6. , main bucket 1
A rotary joint 12 is provided at the center of rotation of the rotary plate 3 , a motor gear portion 13 driven by the oil motor 5 is provided at the bucket attachment portion, and a rotating body gear portion 13 ′ that meshes with the motor gear portion is connected to the rotary plate 3 . established in
The gear part 13 has an axial force tip inclined inward,
The teeth of the motor gear part 13 are meshed with the teeth of a rotor gear part 13' formed inside the rotary plate 3, the tooth profile of the motor gear part 13 is made into the teeth of a bevel gear, and the teeth are rotated so that the teeth can mesh with the teeth. A drumstick 1 having opposing buckets that can be clamped by meshing teeth formed on a plate 3. This is a rotary plate drive device for use in other equipment.

Next, to describe the effects resulting from the above configuration, a motor gear part is provided in the bucket attachment part, a rotating body gear part that meshes with the motor gear part is provided on the rotary plate, and the motor gear shaft is directed from the upper part of the outside to the lower part of the inside. Since the bucket mounting part is inclined, the motor part of the motor gear part can be easily disposed on the upper surface of the relatively narrow bucket mounting part. Further, since the shaft of the motor of the motor gear portion can be easily moved back and forth and up and down, it is possible to easily adjust the meshing of the gears.
